How the Five Compare on the Numbers
The Tovolo cover measures 10.5 inches by 10.5 inches by 3.25 inches and weighs 0.4 pound. The GLICPIX cover measures 10.5 inches by 10.5 inches by 0.1 inch and weighs 0.3 pound. The Nordic Ware cover publishes a 10.4 inch interior diameter at the lip, a 9.7 by 2.2 inch interior, and a 10.5 inch exterior diameter at 3.1 inches in height, and weighs 0.3 pound. The AIDACOM cover measures 10.5 inches by 10.5 inches and weighs 0.57 pound, with a height that adjusts from 0.8 to 3.2 inches. The Tusjiain cover measures 11.02 inches by 11.02 inches by 4.72 inches and weighs 0.31 pound.
On diameter, the Tusjiain cover is the largest at 11.5 inches, followed by the Tovolo, GLICPIX, and AIDACOM covers at 10.5 inches, and the Nordic Ware cover at 10.4 inches interior. On weight, the GLICPIX and Nordic Ware covers are the lightest at 0.3 pound, the Tusjiain cover is 0.31 pound, the Tovolo cover is 0.4 pound, and the AIDACOM cover is 0.57 pound. The GLICPIX cover is the only one that publishes a heat limit of 266°F and a 10 minute maximum heating time.
The table does not tell you how any cover performs in a microwave. No one at Lush has used these covers. The figures are what the manufacturer publishes. A published diameter does not guarantee a fit over your specific plate, and a published heat limit does not guarantee the cover will not warp at that temperature.
Collapsible Designs and Storage
Tovolo and AIDACOM
The Tovolo cover collapses from 3.25 inches to 0.75 inch. The AIDACOM cover adjusts from 0.8 to 3.2 inches. Both publish a collapsed height, which lets you compare storage thickness directly. The Tovolo cover is 0.4 pound and the AIDACOM cover is 0.57 pound. The AIDACOM set includes a silicone mat that measures 10 inches, which adds a second item to store.
The Tovolo cover doubles as a colander. The AIDACOM cover does not list colander use, but the included mat works as a trivet, pot holder, spoon rest, or drying mat. If you want one item that drains produce, the Tovolo cover is the pick. If you want a cover plus a surface to set hot dishes on, the AIDACOM set is the pick.
GLICPIX and CasaCulina
The GLICPIX cover publishes a height of 0.1 inch, which is its collapsed height. It does not publish an expanded height. The CasaCulina cover folds to 1.2 inches and pops up to 3.2 inches. Both are collapsible, but only the CasaCulina cover publishes both the folded and expanded heights. The GLICPIX cover weighs 0.3 pound and the CasaCulina cover weighs 0.67 pound.
The GLICPIX cover publishes a 266°F heat limit and a 10 minute maximum heating time. The CasaCulina cover does not publish a heat limit. If you need a published temperature ceiling, the GLICPIX cover is the only pick that provides one. The CasaCulina cover is a two-pack, so you get two covers for the same storage footprint.
Heat Limits and Materials
Published temperature limits
The GLICPIX cover is the only pick that publishes a heat limit: 266°F (130°C). It also publishes a maximum heating time of 10 minutes. No other cover on this list publishes either figure. The Tusjiain cover states it should not be used in grill or convection mode, which is a restriction but not a temperature limit. The Tovolo, Nordic Ware, AIDACOM, and CasaCulina covers do not publish a heat limit.
If your microwave use stays within 10 minutes at a time, the GLICPIX cover publishes the numbers to match. If you reheat for longer, no cover on this list publishes a time limit, so you cannot compare them on that basis. The manufacturer does not publish that figure for the other four.
Silicone versus plastic
The Tovolo cover is silicone. The GLICPIX cover is PP and TPR. The Nordic Ware cover is plastic. The AIDACOM cover is PP plastic with a silicone mat. The Tusjiain cover is food grade plastic. All five state BPA free. The Nordic Ware cover also states melamine free. The Tusjiain cover states melamine free.
Silicone covers are flexible, which is why the Tovolo cover can collapse. Plastic covers hold a rigid shape. The Nordic Ware cover publishes a 10.4 inch interior diameter at the lip, which is the only interior measurement on the list. If you need to know the space under the cover, that is the only published figure.
Which One Fits Your Kitchen
If you want a cover that stores flat and drains produce. The Tovolo cover collapses to 0.75 inch and doubles as a colander. It is 10.5 inches in diameter and weighs 0.4 pound.
If you need a published heat limit. The GLICPIX cover publishes 266°F and a 10 minute maximum heating time. It is 10.5 inches in diameter and weighs 0.3 pound.
If you want two covers with a published interior diameter. The Nordic Ware set includes two covers with a 10.4 inch interior diameter at the lip. Each weighs 0.3 pound.
If you want a cover plus a mat. The AIDACOM set pairs a 10.5 inch cover with a 10 inch silicone mat. The cover adjusts from 0.8 to 3.2 inches and the set weighs 0.57 pound.
